Subject: 0008 Tex backslash
Version 3.1.20 contains an irritating bug when using latex that causes all
sorts of problems when the backslash is used. (The backslash is a common
character in latex that is used, among other things, to create a forced space
similar to the tilde character.) In the current version, 3.1.20, the next TWO
characters are skipped after a backslash. This can results in misspellings and
the file being incorrectly parsed. (For example, if the text contains the
sequence `\ $' math mode will not be entered until the matching $ which should
end it, resulting in the body of the text not being spell checked and the math
region being checked.)
Make sure to undefine NO8BIT and use a larger number for MASKBITS if you are
using iso character sets.
